RIKEN Research Summer issue


A quick post to let you know that the Summer issue of RIKEN Research Magazine came out towards the end of June. This issue covers brain evolution, regenerating skin, super-clear synapses, and much much more! Enjoy!

Pulses of light can enhance superconductivity


Pulses of light could be used to turn materials into superconductors through an unconventional type of superconductivity.

Microbial infections are a parasitic plant’s dream


Parasitic plants use quinones produced by their host to attack. Now we know that crops produce quinones as an immune response against microbial infection. How can we protect crops from both kinds of attack?

What’s that smell? The advantage of sniffing


Rhythmic sniffing boosts phase-coded neuronal signals in the mouse olfactory bulb that allow odors to be identified.

Zebrafish imagine a danger-free future to avoid threats in virtual reality


By imaging the brain while zebrafish “swim” in virtual reality, scientists have learned that even fish can create internal models to predict future outcomes.
